Do I own the domain name that I've registered?

Legally, you only own a license to use the domain - you do not gain title to it. However, for all practical purposes, the end result is the same. As long as the name has nothing to do with someone else's trademark or legal right to own the name, you essentially own the domain name that you registered through us. In fact, in InterNIC's jargon, you are the administrative contact for your domain, i.e. you are the person who can speak on behalf of the organization for which the domain name is registered. You should be able to answer non-technical questions about the organization's plans for the name and procedures for establishing sub-domains. You should also be able to represent the organization regarding use of the name.
We recommend that you familiarize yourself with the respective Terms, Conditions and Policies issued by the Registrar. This agreement lists some of the conditions by which your domain name will be maintained and highlights their policy name disputes, including possible trademark infringement issues.
